@jaalto1 You can find some helpful steps in the SRanipal get started guide included with the SDK download.

Download the SRanipal SDK

Import the Unity plugin (.unitypackage) into the Unity project

Open the sample scene and play in editor or build

Check eye tracking works in sample scene and robot eyes are green in notification tray

@Corvus Hi! I have followed the getting started guide in the SDK download. Neither of the eye sample scenes work, they both crash when trying to open them. The runtime is installed as well. How can I solve this issue? Thanks for your support.

I have OpenXR enabled an Play Mode Open Runtime set to SteamVR.

Hello there. I createted a new topic, but I will ask the questions here just in case.

I have been searching for these information below, but I can not find the follwing topics.

1.Relationship and Calculation Method between LensOrigin and GazeOrigin.
I have seen the attached picture, but I have not understand the coordinate systems between LensOrigin and GazeOrigin.
Where can I get information that explains how to calculate the eyes angle?
 

2.Design Values for LensOrigin and SystemOrigin
Could you tell me the design value for LensesOrigin and SystemOrigin?
The Lense knob can be changed, so is only the z coordinate of Lens Origin of variable?
If so, does the number of the distance displayed in a image of HMD when changing the distance of lenses show the z-distance from the system origin to lense origin?

3.Relationship between Lens Origin and Screen Coordinates
Where can I get information about the relationship between Screen coordinates and Lens Origin?

If the z direction of Lens Origin is variable , does it affect the gaze angle in the screen coordinates?

 

Moreover, It would be helpful if anyone share documents about the coordinate systems about VIVE PRO EYE.

Thanks.

@CorvusWhere can I find eye tracking module firmware? I want to try to update it. As I'm having a problem "eye camera version N/A". Although the device is plug in and running, with eyechip show in the device manager.

Thank you in advance.
